' SPECIFICATION forming part of Letters Patent No. 738,612, dated September 8, 1903.

I Application filed April 24, 1901. Serial No. 57,334. (No model.)

To alt whom it may concern.-

Be it known that I, ESPIRIDlON HIPOLITO, a citizen of the United States, residing at Los members of window-sash, screen-frames, and

doors in which a number of uniformly-spaced holes are to be bored; butit is applicable for other uses.

My invention is applicable for multiple borlug-machines in which a plurality of boringbits are employed; but in view of. the fact that it is not new in the art to simultaneously operatea plurality of boring-bits I shall illustrate my invention herein simply as applied away to contract the, View. Fig. Ilis a front elevation of the carrier and its support, parts of which are broken away to contract the View. Fig. III is a sectional plan of the machine on line indicated by III III, Fig. IV.

My newly-invented boring-machine comprises an upwardly-directed vertical rotary.

to carry the article to be bored and f u rnished with a suitable passage (1 for the bit, and suitable means for operating the carriage vertically. Said means may be of any desired character; but in the drawingsIhave shown a resilient support composed of springs e, ex-

tending between two yokesf g, one of which, f, is pivotally connected with the carrier h of I the carriage. Preferably the pivotal connec- .tion between the yokefand the carrier h of the carriage is formed by a link t', a. boltj fastening the link vi to the carrier h and a boltlt fastening the link 1' to the yoke f. The up-' 'per yoke g is pivotally fastened toa hanging support, such as the link m, by means of a pivot-bolt n. The hanging-link m is fur- ,nished with a series of holes 0, by means of which the yoke 9 may he mountedatahigher t or lower level, as desired, for increasing or decreasing the tension of the springsein order to adjust the machine for easy operation with myself to such means of adjusting the tension of'the springs. The boring-bit (1 extends upward coaxial of the rotating shaft 6, and the resilient support e allows the carriage to be depressed to bring the article to be bored into contact with the hit.

the gage-bar t is adjustably fastened upon the pins or supports 1;.

The support-pins o are clamped to the vertioallymoving carrier h by means of setscrews w.

The front face of the gage-bar t is preferably corrugated with sharp horizontal corrugations, as shown in Fig. IV, and the clamping-cam u is likewise furnished with horizontal corrugations. When the article to be bored is clamped between the gage-bar t and the clamping-cam u, the corrugations will hold the article to the carriage, so that as the carriage is lowered the article to be bored will be forcibly carried downward to engage the upper cutting end ofthe rotary cutting-bit. By arranging the corrugations horizontally they will engage with the wood lengthwise of the grain, thereby entering it more readily and affording a better hold, and at the same time they will do less damage to the wood than where the indentations are made across the grain. It also decreases the liability of moving the material when the cam is being rotated to clampit in position. The carriage floor or shelf 3 is adjustably mounted to move forward and back onthe horizontal supportpins '0. p

'31 indicates set-screws for clamping the floor s to the support o.

The springs e normally hold the carriage above the boring-bit, and in practical operation the sash stile or rail or other article to be bored will be laid in place upon the supporting device 8, and the "treadle r will be forced down to depress the carriage to bring the article down upon the cutter of the boring-bit, and the boring then takes place, the cuttings falling out by gravity, and thus clearing the hole which is being bored. Any suitable means may be provided for determining the length of the cut-that i-sto say, the depth of In the drawings the down ward movement of the carriage is determined by the stroke of the treadle 7", said stroke being long enough to allow the carriage to be depressed sufficiently to cause the boring-bit to bore the hole to the required depth. In practice the stile or other article to be bored will be placed on the carriage and will he slid along the carriage to be brought into siderable length fastened to the end of the boring position.

z 2 indicate vertically-moving spring-operated retractible stops adapted to project upwardly above the level of the floor 8 winter- These stops may be of different forms, and preferably two forms of stops are provided for each carriage. In Fig. V, I

have detailed the form of stop for use in the main body of the carriage.

The stop there shown consists in a bolt 1, mounted to slide vertically in a case or barrel 2 and upheld by a spring 3, which is contained within the chamber of the case 2. Said case is furnished at its opposite ends with shoulders 4 5. The

shoulder 4 intercepts the shoulderfG on the bolt, and the shoulder 5 supports the spring 4, which presses up against the shoulder 6 of the bolt. In the drawings the shoulder 5 is shown as a plug screwed into the case 2. Said case is screw-threaded at its upper end and is screwed into a screw-threaded hole 7 in the door 8, so that the stop-bolt 1 will project about a'quarter of an inch, more or less, above the top of the floor 3. Each spring 3 normally upholds the bolt 1 of its stop, and the several stops are arranged in a line parallel with the gage-bar 2f, which line intersects the extended axis of the boring-bit, so that when'one hole has been bored the operator may lift the front end of the stile or other article and bring it onto the top of the stop .2 and allow its weight to rest thereon, therebyv to depress the stop to a level with the top of the floor 5. Then the stile or other article will be slid along the floors until the hole which has just been bored in said stile or other article comes above the bolt 1, whereupon said bolt will be forced upward by the spring 3 and will enter the hole .which has been bored in the article and will thus stop the article and prevent it from being pushed forward until it-is again raised above the top of the bolt. The stops are arranged at such distances from the extended 11 indicates a nut screwed on the stem of the bolt 1, and the link 8 is mounted on said stem between the nut 11 and the end of the case2 in which the bolt 1 is contained. When the link 8 is adjusted to bring the thick portion 9between the end of the case 2 and the shoulder formed by the nut 11, the bolt will the withdrawn to bring the upper end of the bolt flush with the top of the floor s. the link is adjusted to bring the thin portion :10 thereof b'etween the end of the case and the shoulder formed by the nut 11, the spring When 3 will throw the boltup into the position indicated in Fig. IV to stop the article to be bored.

The stop ,2 consists in a spring-arm of confioor or shelf 5 and projecting therefrom and upbent at its outer end to project above the level of the floor s.

cept the article to determine its position at the time of boring, thus to boreholes where desired.

preferably made short, so that when they are drawn back out of the way they will not project so far beyond the edge of the table as to be in the way or be liable to be broken off. As they move freely in the grooves, they can The stops are I be quickly moved forward to engage with the piece of material being operated upon and as a I quickly, moved back out *of theway, as soon as the first hole is bored and it is desired to movethe material lengthwise for the pin to enter the hole ,tohold the material for the 1 next hole.

It is to be understood that the parts of the carriagewhich are onhopposite sides of the as required. The stops 2; are to be at such distances from the extended axis of the boring-bit that when a hole has been bored and thegarticle isslid along the stop will enter the a hole andistop the article when it is in position for the boringof a second hole.

maybe arranged as required for the work to beperformed .by the, machine. Thesliding comesagainst the sliding stopj12.

stops12 are designed for stopping the stileof a door or window frame or other frame in,

which the stile of the unfinished door is longer thantrequired in the finished door -that is to say, it is customary with the stilesof doors, &c.,-jtoleave a projecting part "which can be, cutoifminfinishing the door-thus to remove any, marring or splitting; of the ends of the. 3

In practicalwork the operator will adjust j the latches 8 to holdtheir appropriate bolts 1 in the required adjustment to form thestops forthe work in hand. 1 If a door or window stile isto be bored, thesliding stop 12 will first beslid into position to stopthe stile. Then thestile will {be laid upon the floor 8 above thespring-supported stopsz, which it will de-1 above the bolt 1, which will thenbe thrown up into said hole, thus stopping the stile in position for the boring of the next hole. Then the operator will again depress the carriage to bore the next hole.

At each downward movement the operator will hold the cam u,

, to clamp the stile.

Thespring-bladed stop 2' is adj nstably and detachably fastened to the shelf or floor 8 by a screw 15 and is adapted to support the ends I of long door-stiles and thejlike and to stop; 1 the same appropriately. The upturned end of thisstop may be adapted to enter the bored hole the same as stops 2.
